Why do I need to change my air filter?

There are several reasons you should change your air filter on a regular basis. While the recommendation for the frequency you should change your air filter can vary, every 90 days is an approximate estimate. Your location, usage of your HVAC system, whether you have pets or not, age of equipment, and other factors can all contribute to the appropriate frequency of changing your air filter. It doesn’t hurt to change your air filter too often, but there can be consequences of changing it too late. Check with a professional for a personalized recommendation on how often you should change your air filter. In the meantime, if you need some motivation to change your air filter, here are some of the benefits of maintaining a clean HVAC air filter. 

  1. Improve air quality in your home: Air filters have a direct impact on the quality of air entering your home when your HVAC is running. The purpose of the air filter is to clean the air circulating through the HVAC system. A dirty air filter can interfere with the ability of the air filter to do its job. It can also cause trapped grime to be released into your home. With much of our time spent indoors, it’s important to maintain good air quality. Indoor air quality is often worse than outdoor air quality. 
  2. Improve energy efficiency: A clean air filter can help your system operate more efficiently. Dirty air filters can cause the HVAC system to work harder as it tries to push air through your system. The more efficient your HVAC system can run, the more you can save on your utility bill.
  3. Extend the lifespan of your HVAC unit: Maintaining a clean air filter and performing regular maintenance can help your HVAC last longer. Dirty air filters can cause the system to work harder and potentially clog up your HVAC unit. 
  4. Reduce the likelihood of repairs: Repairing your HVAC system can be just as costly as replacing it in some cases. To reduce the likelihood of repairs, perform regular maintenance, including changing your air filter on a regular basis. 
  5. Improve temperature control: Changing your air filter regularly promotes greater efficiency. Your system can work to produce the right amount of hot or cold air and air can pass through easily. This allows you to have more control over maintaining a consistent temperature for your home.
